CAUTION: Do not use bulbs other than those listed
in the Bulb Application Table. Damage to lamp can
result. Do not touch halogen bulbs with fingers or
other oily surfaces. Bulb life will be reduced.

BRAKE LAMP SWITCH
DESCRIPTION
The plunger type stop lamp switch is mounted on a
bracket attached to the brake pedal support.
CAUTION: The switch can only be adjusted during
initial installation. If the switch is not adjusted prop-
erly a new switch must be installed.
OPERATION
The brake lamp switch is used for the brake lamp,
speed control and brake sensor circuits. The brake
lamp circuit is open until the plunger is depressed.
The speed control and brake sensor circuits is closed
until the plunger is depressed.

DIAGNOSIS AND TESTING - BRAKE LAMP
SWITCH
The brake lamp switch can be tested with an ohm-
meter. The ohmmeter is used to check continuity
between the pin terminals (Fig. 1).
SWITCH CIRCUIT IDENTIFICATION
• Terminals 1 and 2: brake lamp circuit
• Terminals 3 and 4: RWAL/ABS module and Pow-
ertrain Control Module (PCM) circuit
• Terminals 5 and 6: speed control circuit
SWITCH CONTINUITY TEST
NOTE: Disconnect switch harness before testing
switch continuity.
With switch plunger extended, attach test leads to
pins 1 and 2. Replace switch if meter indicates no
continuity.
With switch plunger retracted, attach test leads to
pins 3 and 4. Replace switch if meter indicates no
continuity.
With switch plunger retracted, attach test leads to
pins 5 and 6. Replace switch if meter indicates no
continuity.
REMOVAL
(1) Disconnect switch harness (Fig. 2).
(2) Press and hold brake pedal in applied position.
(3) Rotate switch counterclockwise about 30° to
align switch lock tab with notch in bracket.
(4) Pull switch rearward out of mounting bracket
and release brake pedal.
INSTALLATION
(1) Press and hold brake pedal down.
(2) Align tab on new switch with notch in switch
bracket. Then insert switch in bracket and turn it
clockwise about 30° to lock it in place.
(3) Connect harness wires to switch.
(4) Release brake pedal.
(5) Move the release lever (Fig. 2) on the switch to
engage the switch plunger. The switch is now
adjusted and can not be adjusted again.

COMBINATION FLASHER
DESCRIPTION
The combination flasher is located in a dedicated
connector on a take out of the instrument panel wire
harness, located under the instrument panel just out-
board of the instrument panel steering column open-
ing (Fig. 3). The combination flasher is a smart relay
that functions as both the turn signal system and the
hazard warning system flasher. The combination
flasher has fourteen blade-type terminals that con-
nect it to the vehicle electrical system through four-
teen matching cavities in the instrument panel wire
harness connector; however, only ten of the combina-
tion flasher terminals are used in this application.
The combination flasher contains active electronic
Integrated Circuitry (IC) elements. This flasher is
designed to handle the current flow requirements of
the factory-installed lighting. If supplemental light-
ing is added to the turn signal lamp circuits, such as
when towing a trailer with lights, the combination
flasher will automatically try to compensate to keep
the flash rate the same.
The combination flasher cannot be repaired or
adjusted and, if faulty or damaged, it must be
replaced.
OPERATION
The combination flasher has fourteen blade-type
terminals, but only ten are used in this application.
These ten terminals are intended for the following
inputs and outputs: fused B(+), fused ignition switch
output, right turn signal sense, left turn signal sense,
hazard flasher signal, brake lamp switch output, and
two outputs each for the right and left turn signal
circuits. Constant battery voltage is supplied to the
flasher so that it can perform the hazard warning
function, and ignition switched battery voltage is
supplied for the turn signal function. The Integrated
Circuit (IC) within the combination flasher contains
the logic that controls the flasher operation and the
flash rate. The IC receives separate sense ground
inputs from the multi-function switch for the hazard
flasher, right turn signal, and left turn signal. A spe-
cial design feature of the combination flasher allows
it to
9sense9 that a turn signal circuit or bulb is not
operating, and provide the driver an indication of the
condition by flashing the remaining bulbs in the
affected circuit at a higher rate (120 flashes-per-
minute or higher). Conventional flashers either con-
tinue flashing at their typical rate (heavy-duty type),
or discontinue flashing the affected circuit entirely
(standard-duty type).
Because of the active electronic elements within
the combination flasher, it cannot be tested with con-
ventional automotive electrical test equipment. If the
combination flasher is believed to be faulty, test the
turn signal and hazard warning system. Then
replace the combination flasher with a known good
unit to confirm system operation. (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING

EXTERIOR/TURN
SIGNAL & HAZARD WARNING SYSTEM - DIAG-
NOSIS AND TESTING).
